[syslinux] PXELinux over Ris server
Having the same trouble that Mark (
http://www.zytor.com/pipermail/syslinux/2002-March/000244.html)
had over a test platform I have here. Having a redhat 7.3 with dhcp
V3.0rc12 and atftp (0.6.2) on a local
small hub and a W2k Server with RIS installed.
If I stop binlsvc on nt server my network boot run ok to pxelinux,
but as soon as binlsvc is started, RIS server always respond over
my local network (dhcp and dns stopped on nt server)
Try to use option vendor-class-identifier "PXEClient" or next-server
option to route to the correct tftp-server, but does not work !
Is there something special to set with mcast_adrr parameter ?
What does signify address range: 239.255.0.0-255 for multicast ?
Thanks for your help.

I don't know any general way to switch this off, since this is implemented by the boot rom itself. Maybe you need to set some special options, but this should be documented in the PXE rom's documentation (usually there isn't any documentation about the PXE rom despite that the PXE rom exists ....). So you could try some options, and see if the rom still sends out a PXE request (Port 4xxx instead of the usual DHCP ports, the packet looks like a DHCP request).>From my point of view the invention of the 'PXE server' isn't useful at all, if someone needsto specify the bootfile independent of the IP address you could always generate a dhcp config from two sources.
